Coming from Santa Cruz, I was sorely disappointed with Monterrey. I ordered the lunch special #4 (taco, chile relleno, beans, and rice) and there was nothing special about it. The bean were mush. I've had canned beans with more texture and better flavor. The rice was salty. The chile relleno was profoundly sub-par having very little chile to it. I also couldn't tell if it had been fried or not. The sauce that went with it was okay, but not close to the chile relleno at Las Palmas in Santa Cruz. The taco looked like it needed a lot of love. The meat was oddly seasoned and had gross, mushy texture to it. The taco shell itself was probably store bought. Ick.
Overall, if I do go back I'm trying something else.
